On my 13700k with thermalright contact frame, and Arctic Liquid Cooler II 360mm AIO, thermal grizzly paste, despite the contact frame which helped reduce the temps of all cores, P5 is still 15-20C higher than most of the other P cores. In XTU P4 and P5 are starred, so are the best performing onces. I undervolt by 0.115V. The “chips” rating by my Z790 Elite AX gigabyte motherboard is 93. Finally, I pipe in cold outside Canadian air to blow on open PC.
Any suggestions on what I can do to improve this? Or is this “Normal” All other posts I’ve read suggest this isn’t normal.
Current temps on full load: P0 68C P1 71C P2 67C P3 85C P4 70C P5 91C P6 69C P7 78C. The E cores are all 62-64C. Clocks on full load: 5.3GHz all P cores. Power 195W Vcore 1.164V.
With that large temperature delta between most P-Cores and the two hot ones, my suggestion is to take a closer look at how the thermal paste is distributed over the CPU surface and see if the “pump-out” effect has caused the paste to be too thin in the middle .
